Thieves Guild stuff. Not going to spoiler.
So, Tonilia has been glitched for me from an early stage in the Thieves Guild quest line because I sold my Guild armor to her. At one point I'm told to talk to her and get it upgraded - but since I don't have it, she can't upgrade it, and she wouldn't ever talk about anything else, all the way through the quest line. Nothing.
Last night I had done 3/4 of the special quests and check in with her and huzzah! she is saying something different. She sends me on a little quest to deliver moon sugar to some traders to set up supply routes for the Guild. I do that, and knock off the final special quest to rebuild the Guild (in Markarth this time), and come back the the ceremony to become Guild Master.
I head to Tonilia to finish up her quest, but all she'll tell me is to go talk to Byrnoff. I do, we do our thingy, then he tells me to go back and talk to Tonilia.
When I get back to her....she's back to asking about the fucking Guild armor upgrade again. You know, the armor I sold to her. So now I can't 1) complete her quest, 2) complete rebuilding the Thieves Guild, or 3) get the Achievement for doing so, because all she'll do is berate me for not having my Guild armor. Which is what she's been doing for about 100 of my 130 hours of play.
The only way I can think to un-break this is to grind lockpicking up to 100 and steal some off of one of the other Guild members. Naturally, it's at 21 right now, and I'm level 47.
Pending that, does anyone have any ideas how to un-break her? Mind-blowing that such a simple thing could break the entire quest line like this.
